Abstract

The present invention provides a charge tyre which forms concentric circles shape thin-small grooves on the tyre surface to improve the running performance on the ice and snow ground in the using early days of the new product before playing the performance of the tyre surface compound. The tyre veins channel (14) forms on the massive pattern (12) of the tyre surface part (10), and multi thin-small grooves (16) form on the tyre surface part (10) pattern, the width of the groove is 0.1~2mm, the depth is 0.1~1mm, the distance between two grooves is 0.5~4mm.

Description

Air-inflation tyre

Technical field

The present invention relates to air-inflation tyre.In more detail, relate to a kind of for before the performance of performance tread compound, use initial stage to improve the ice-snow field rideability and form the air-inflation tyre of the tiny groove of concentric circles on the surface of fetus face.

Background technology

Existing nothing nail snow tire (Studless tire) adds bubble and various material in order to improve the rideability on ice and snow road on tread-rubber, form tiny concavo-convex on the surface of fetus face.But it is found that at the wearing and tearing initial stage, do not form tiny concavo-convexly on the surface of fetus face, existence can not be brought into play the defective of original rideability.

In order to solve this defective, people have adopted the means that the tiny groove as slit (Slit) is set in new tire.。

For example, in Japan's flat 05-330319 patent disclosure communique, provide following tire.That is,, form sipes per tire for when using new tire, bringing into play good ice-snow field rideability under the condition of the rigidity of not damaging block-type tread.Be arranged in parallel the auxiliary sipes per tire of 10%～45% degree of depth h2 with main sipes per tire degree of depth h1 of the main sipes per tire that forms in central authorities and the end of block-type tread.

In addition, in Japan's flat 07-186633 patent disclosure communique, advised not having to improve than existing tire under the condition of variation the deceleration and stopping performance on the wet road surface of ice-snow field and the tire of driveability in other performance.On block-type tread, tiny rib is set in order to reach this purpose along tire width direction.The width of described tiny rib is 5 μ m～2.0mm, highly is 5 μ m～1.0mm, is spaced apart 5 μ m～1.5mm between the tiny rib of adjacent circumferencial direction.

In Japan's flat 09-323511 patent disclosure communique, advised following tire.That is, at the tire of giving full play to the ice-snow field rideability in when design under the condition of not destroying the Pattern Design degree of freedom at the use initial stage, for example, applicable to the tire that does not have nail snow tire, mud-and-snow tyre, all-year tire.These tires have the auxiliary sipes per tire of main sipes per tire and disconnected this main sipes per tire of crosscut.Degree of depth that should auxiliary sipes per tire is 0.02～0.03 times of block-type tread length of tire circumferential direction.The length of block-type tread is 10～15 with respect to the gap length ratio of the tire circumferential direction between the auxiliary sipes per tire, so can know have 10～15 tiny grooves in a block-type tread.

In addition, in Japanese 2000-301914 number, 2004-034902 number, 2004-034903 patent disclosure communique, for the rideability on the ice-snow field of bringing into play tire, width, the degree of depth and the distance between it etc. to slit limit, and decorative pattern shape and angle etc. are also limited.

But as previously mentioned, by at slit (Slit) angle (Angle) being set, the method for the slit (Cross slit) that perhaps adopt to intersect etc. improves the ground connection power of longitudinal and transverse direction.But the angle that suitably works on slit under most of situation is restricted, thereby can not give full play to the performance that tire travels at ice-snow field.

Summary of the invention

Therefore, the present invention is different with the slit that has restricted directivity in the prior art, the object of the present invention is to provide a kind of air-inflation tyre, for the surface in new tread of tyre portion forms tiny concavo-convex, improving the rideability on the ice-snow field road surface in the wear on tyres initial stage, in this tread of tyre portion decorative pattern, be formed with the tiny groove of concentric shape.

The specific embodiment

Air-inflation tyre of the present invention is formed with a plurality of tiny grooves with concentric shape on the fetus face decorative pattern, the width of its groove is 0.1～2mm, and the degree of depth is 0.1～1mm, and the distance between the tiny groove is 0.5～4mm.

The tiny groove of described concentric shape can be different shapes such as concentric circles, quadrangle from outside to inside, rhombus, triangle, pentagon.

Below, the present invention is described in detail with reference to the accompanying drawings.

Fig. 1 is the airtyred birds-eye view that is formed with the fetus face decorative pattern of concentric circles, concentric rhombus and concentric dimetric tiny groove of the present invention.

10 expression tread of tyre portions in Fig. 1,12 expression block-type treads, 14 expression sipes per tires, the tiny groove of 16 expressions.

Air-inflation tyre of the present invention is formed with sipes per tire 14 on the block-type tread 12 of fetus face 10, and further be formed with a plurality of tiny groove 16 with concentric shape, the width of described tiny groove 16 is 0.1～2mm, the degree of depth is 0.1～1mm, and the distance between tiny groove 16 and the tiny groove 16 is 0.5～4mm.

The tiny groove 16 of described concentric shape can be concentric circles as shown in Figure 1, from the outside inside quadrangle, rhombus, in addition, can have different shapes such as triangle, pentagon.But the shape of tiny groove is not limited to the above-mentioned shape that limits.

The present invention is in order to improve the Pavement Performance when ice-snow field travels in the Tyte Wear initial stage, in the fetus face decorative pattern, form the tiny groove of concentric circles, quadrangle or rhombus, be absorbed in water on the road surface when travelling on the ice-snow field by small groove, can improve the performance on the ice-snow field road surface, by the ground connection power of edge effect raising on the road surface.

Air-inflation tyre of the present invention is by the tiny groove of the concentric circles different with existing tire, make tire and road surface have angle of slide, even and change in the angle between road surface and the tire and also on whole angle, effectively to play effect, at tire or do not have on the tread bar of directivity all applicable with directivity, and, can improve the controller performance of tire on the various directions of craspedodrome and revolution etc.

Claims

1. air-inflation tyre, on the block-type tread (12) of fetus face (10), be formed with sipes per tire (14), it is characterized in that, on the block-type tread (12) of described fetus face (10), further be formed with a plurality of tiny groove (16) with concentric shape, the width of described tiny groove is 0.1～2mm, the degree of depth is 0.1～1mm, and the distance between the described tiny groove is 0.5～4mm.
